:: Assignment Reflection 20190722
:: 
:: I was overthinking this assignment to a huge degree before
:: I read the type-checking docs in section 2.2 and sanity-checked
:: myself — I think I got too stuck with trying to replicate the 
:: code demonstrated in the "conditionals" walkthrough
:: and added too many layers of t/f checking before
:: landing on the below solution, remembering that the assignment
:: was to produce a naked generator

|=  arg=*
?^  arg  
  "arg is a cell"  
?:  =(0 (mod arg 2))  
  "arg is an even @"  
"arg is an odd @"
